Prime Minister Sanae Takaichi speaks to reporters ahead of her trip to Vietnam and Australia, at the prime minister’s official residence in Tokyo on May 1, 2026.

Japanese Prime Minister Sanae Takaichi has unveiled a diplomatic policy centered on strengthening Japan’s economic security. During the recent Golden Week holiday, she toured Vietnam and Australia and called for cooperation to bolster supply chains for strategic materials.

At the foundation of the policy is the “Free and Open Indo-Pacific” (FOIP) initiative advocated in 2016 by then Prime Minister Shinzo Abe. It aims to boost the regional economy while promoting the principles of the rule of law and free trade.

Takaichi stressed her belief that nations in the region can become “stronger and more prosperous together.” What she put front and center was a framework in which like-minded countries work together to secure energy and critical minerals.

China is stepping up its economic coercion using rare earths. The aim of countering this kind of “weaponization of the economy” by a major power is understandable.

In Vietnam, Takaichi stated that Japan would support crude oil procurement in response to the de facto blockade of the Strait of Hormuz. A joint statement issued in Australia included assistance for the distribution of liquefied natural gas and coal. On the security front, she also indicated a policy to provide defense equipment free of charge to partner countries.

However, the effectiveness of these policies is unforeseeable. It requires enormous time and money to build supply chains for scarce resources, from their development and production to distribution. Relationships of trust among participating countries are indispensable.

In this regard, the behavior of the United States, which has been expected to play a central role in the FOIP, has become a source of concern. The Donald Trump administration, which prioritizes its “America First” doctrine, has imposed high tariffs even on allies. The U.S. has launched an attack on Iran in violation of international law, shaking the international order.

Japan and other countries have inseparable economic ties with China, and it is difficult to pursue development without the country. If the exclusive nature of an “anti-China coalition” is brought to the fore, it will be difficult to secure support from countries caught between the U.S. and China. It could also heighten regional tensions.

Regardless, it remains unclear how the Takaichi administration views its China policy. Japan-China relations worsened after the prime minister’s controversial remarks in November last year about a potential Taiwan contingency and moves to reopen dialogue are nowhere in sight. Parliamentary diplomacy and private-sector exchanges are also sluggish.

What matters is how Japan can contribute to regional stability. The prime minister needs to forge diplomacy grounded in a broad, comprehensive perspective.
